Hmm. It rather looks to me like this
cmp = DatumGetInt32(FunctionCall4(&ginstate->comparePartialFn[attrnum],
should be this
cmp = DatumGetInt32(FunctionCall4(&ginstate->comparePartialFn[attrnum-1],
which leaves me with even less of a warm and fuzzy feeling about
matchPartialInPendingList() than I had before. How much has that code
been tested at all? It seems quite clear that it's not exercised by
any regression test ...
